May is our recommended month at Theodore Roosevelt: the lightest crowds of the park's good-weather months.

The daily average of about 53°F is a comfortable range for hiking and being outdoors all day. These figures are 1991–2020 NOAA climate normals from the nearest station, about 9.7 miles from the park.

Because June, July and August together draw about 61% of annual visitors, choosing May instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 14.9 hours of daylight in May to explore — between the 8.3-hour midwinter low and the 15.7-hour summer high.

Park-wide, 2025 drew 729,893 recreation visits, about flat from 732,951 in 2024.
